It is primarily evaluated using events containing a pair of muons from the decay of Z bosons. The efficiency of the single-muon trigger is measured for muons with transverse momentum 25 < pT < 100 GeV, with a statistical uncertainty of less than 0.01% and a systematic uncertainty of 0.6%. The pT range for efficiency determination is extended by using muons from decays of J/Psi mesons, W bosons, and top quarks. The muon trigger shows highly uniform and stable performance. The performance is compared to the prediction of a detailed simulation. %R 10.1140/epjc/s10052-015-3325-9 %U http://arxiv.org/abs/1408.3179 %U https://doi.org/10.1140/epjc/s10052-015-3325-9 %P 120-31pp
